Thank you, Dave. The question appiars because some guys posted that they ordered Robart struts for SpringAir retracts. So I was wondered that complete system not includes struts.
May be you also know what's wrong is with their tail retract for TF GS P47? Everyone said that they are not happy of SA tail and ordered Robart's one. I've never found the pictures of tail retract on the SA website. May somebody can post it.
